VEHICLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 772,818, dated October18, 1904.

Application filed July 30, 1903. Serial No.'16'7,608. (No model.)

To all' whom, it hay concern:

Be it known that I, CHARLES OLSON, a citizen of the United States ofAmerica, and a resident of Des Moines, Polk county, Iowa, have inventeda new and useful Cushion Vehicle-Tire, of which the following isa'specifcation.

The object of this invention is to provide an improved construction forvehicle-tires.

A further object of this invention' is to be found in the provision of acomposite substance of yielding, compressible, elastic,ex pansive, andcohesive characteristic for-use in the construction or formation ofvehicletires.

A further object of this invention is to'he found in the manufacture ofvehicle-tires from a cohesive, resilient, compressible, expansive, oryielding substance having incorporated therein strips of wire-cloth.

My invention consists in the substance or composition of matter for useAin the manufacture of vehicle-tires,"which composition of mattercomprises wire-cloth filled with cohesive, resilient, compressible,expansive, or yielding substance'.

MyY invention consists, further, in the construction or manufacture ofvehicle-tires of strips of wire-cloth placed face'to face and theinterstices thereof filledwith cohesive, re-

p silient, compressible, expansive, 'or yieldingY substance.

My invention consists, further, in the manu-V facture of vehicle-tirespartly of rubber and partly of a substance composed of strips of`wire-cloth placed face to face and the'interstices thereof filled withcohesive, resilient, compressible, expansive, or yielding substance.

My invention consists, further, in the manufacture of vehicle-tires of asubstance composed of strips of wire-cloth cut on the ybias and placedface to face and the interstices thereof Viilleb with cohesive,resilient, oompressible, expansive, or yielding substance.

`My invention consists, further, of the manufacture of vehicle-tirespartly of rubber and partly of a composition consisting of sheets o fWire-cloth cut on the bias and placed face to face, the intersticesthereof filled with cohesive, resilient, compressible, expansive, or

yielding substance.-

My invention consists, further, of the manu.- facture of vehicle-tiresof a substance composed of strips of wire-cloth cuton the bias andplaced face to face in such manner that the edges of the strips(composed solely ofend portions of the wire strands of the cloth) arepresented, respectively, to. a wheel-rim and to the tread-surface overwhicha wheel may travel, the interstices of the wire-cloth filled withcohesive, resilient, compressible, or yielding substance.

My invention consists, further, of the manufac-ture of vehicle-tires ofa substance composed of strips of wire-cloth cut on the bias and placedface to face in such manner that the edges of the strips (composedsolely of end porbination of elements hereinafter set forth,

pointed out in my claims, and illustrated by the accompanying drawings,in which- Figure l is a face view of one of the strips of wire-clothemployed in my improved manufacture in its normal unpressed state. Fig.2 is a plan or face view of` the strip of wirecloth shown in Fig. l, thestrands thereof iny rim of the substance illustrated in Figs. 1, 2,

and 3, the tire thus made mounted in a wheelrim. Fig. 7 is across-section illustrating another form of vehicle-tire made of thesubstance described in Figs. 1, 2, and 3 and mounted in a wheel-rim.

In the construction of the composition or f article of manufacture orthe useful device herein set forth the numeral 10 designates a strip ofwire-cloth, preferably cut on the bias in such manner that the strands,warp, and Woof of the fabric cross each other at right angles and extendat oblique angles-preferably forty-five degrees-relative to the marginsof the strip. The ends of the obliquelypositioned wires of the strip,warp, and woof of the fabric are not connected, but extend, as shown inthe other figures of the drawings, to form edges of the complete device.Sheets 1() or strips of the Wire-cloth are positioned face to face andmay vary in width and length as desired. In Figs. 3, 4, 5, and 7 of thedrawings I illustrate the sheets or strips of wire fabric of various andirregular widths, While in Fig. 6 of the drawings I show the sheets orstrips of the same width. It is to be understood that the length of thestrips may be greater or less than the length of a given vehicle-tire.The strips or sheets after they are laid face to face are molded with aquantity of cohesive, resilient, compressible, expansive, or yieldingsubstance 11, such as india rubber, and said substance is compressed orsubjected to pressure in such manner that it will pass within the meshesand interstices of some or all of the sheets or strips 10. The cohesive,resilient, cornpressible, expansive, or yielding substance 11 is thenvulcanized under pressure in a mold or former, or otherwise, to the endthat the composite substance produced by such vulcanizing of thesubstance in contact with the wire fabric will approach as nearly aspossible to a homogeneous condition.

In Fig. 3 I illustrate a strip, block, or article of manufactureapproximating in width to double the thickness desired for the resilienttires, and said article of manufacture may have holes or bores 12longitudinally thereof and notches, grooves, or creases 13 1-1longitudinally of its central portion. In this form of device or articleof manufacture I prefer to employ alternate wide and narrow strips orsheets 10, having their center.` at the eenter of the resultant block,and then cut, rip, or sever the block on the lines of the creases orgrooves 13 14, and thereby produce two strips, blocks, or articlessusceptible of use as vehicle-tires. \Vhcn the block or strip is cut atthe line of the creases or grooves 13 14.-, the cut faces thus exposedform the treadsurfaces of the resultant tire, which tire may be mountedin the channel-rim or otherwise fixed to a vehicle-wheel in any desiredmanner, the bores or holes 12 longitudinally of the tires being providedfor the insertion of bond-wires, as shown in Figs. 41, 5, and 7 of thedrawings. I do not wish to be understood as limited to the use of thebond-wire for fastening' the tires to the wheel-rims, since. manydifferent devices for fastening means are now common and well known andmay be employed interchangealily. It will be observed that the cut facesof the tire resulting from a severance or division of the block shown inFig. 3 and containing the strips of wire-cloth having the wires,threads, or strands thereof positioned obliquely to the tread-surfaceand held together with the cohesive substance will be noiseless and yetcompressible and resilient to a maximum degree, for the reason that thewires, thread, or strands will yield vertically under pressure andimpact and yield relative to each other at the points of crossing, asshown in Fig. 2, and react or recover partly through the resilience ofthe wires, threads, or strands and partly through the resilience of thecohesive substance. This device also has this quality, that the metallicportions of the block, strip, or tire will wear and the cohesiveportions will abrade, spread, and cover the ends ofthe metallicportions, but will not mash or spread to so great an extent as would bethe case if the metallic portions were omitted, and at the same time thefrayed and abraded portions of the cohesive substance will projectbeyond the metallic portions of the trezul-surface and furnish acushion-tread for impact prior to the engagement of the metallicportions.

In Fig. 4 of the drawings .l show a compos* ite block or strip 15composed of sheets or strips of bias-cut fabric 10 embedded in cohesivesubstance and formed with a rounded or transversely-curvcd tread-face,to which the margins of the metallic strips project and an angular innerportion notched at 16 17 in the sides of the block to receive intnrnedanges 18 19 of a wheelri1n 20. In this form of tire I provide aconcavity or longitudinal groove 21 in the inner surface of thecomposite block, and said block or tire may be retained in thechannel-rim by contact of the flanges only or by the use of bond-wires22 in a common manner.

In Fig'. 5 I show a composite block or strip composed of parallel sheetsor strips of biascut fabric 10 embedded in cohesive substance IOO ortire, and each, either, or all of the cushions and tires in the rim maybe connected thereto, bound, or fastened in any desired manner. In Fig.7 I show a composite block, strip, or tire formedof a plurality ofbias-cut sheets `of wire fabric 10, arranged.,approximately parallelwith each other and embedded in cohesive substance, with projections orribs 26 27 mating and fitting in grooves on the inner face of theflanges of a channel-rim 28. In

this construction also I provide a groove or cavity 29 inthe inner faceof the tire, and said tire may be mounted in the channel-rim andretained by contact of the projections, or

ribs 26 27 in the grooves of the wheel-rim orby the useof other means offastening,- such as bond-wires 22.

In each of the constructions shown in Figs. 4E, 5, and 6 I provide anair space or cavity in the interior of the tire, which serves as acushion and increases or augments the yresilience and compressi'bilityof the composite block.

In Fig.v 6 I show a tire 30, of rubber or other suitable material,mounted in a wheelrim 31, where it may be fastened by any desired means.The tire 30 is formed with an annular groove in its outer face, and saidgroove is filled with a composite block composed of bias-cut ystrips ofwire fabric l() embedded in cohesive substance.' In this instance, as inall the others illustrated herewith, the major portion of thetread-surface of the tire is protected by the resiliently-projecting endportions of the warp and woof wires of the-bias-cut fabric.

When bond-wires QQ are employed to secure and retain the complete tirein a wheel rim or channel, such as is illustrated in Figs. 4, 5, and 7,one or more of the sheets or strips of wire-cloth-IO are folded or bentaround and beneath the apertures arranged to receive said bond-wires. Insuch position said folded strips or sheets of wire-cloth serve toprotect the apertures and prevent cutting' of the bondwires through theinner portion of the tire.

For the present, and so far as is now known to me, I employ and willemploy india-rubber for the cohesive, resilient, compressible,expansive, or yielding substance vulcanized in contact with the stripsl0 of wire fabric cut on the bias, as described; but I wish to beunderstood as including in invention the use of any substance which maybe preferred to india-rubber,whether now known or hereafter discovered,or any substance in imitation of india-rubber, such as shoddy, which maybe composed of a mixture of felt and india-rubber or made by are-covering and re-forming of substance composed of'fabric and,indiarubber, since numerous commercial articles are now made from suchshoddy and for some purposes have been found to approximate closely topure india-rubber in utility.'
